harness-customize

What problem does it solve?

It eliminates the guesswork of changing agent or workflow behavior by generating the correct per-skill TOML override files and guiding verification against your installed Harness setup.

Core Features & Use Cases

• Discovers customizable Harness skills by scanning installed skills for [agent] and/or [workflow] customization surfaces and reporting which already have team/user overrides.
• Routes changes to the correct surface (agent vs workflow) based on what the user wants to modify and what the target customize.toml exposes.
• Authors sparse, correct TOML overrides under {project-root}/_harness/custom/ with proper merge semantics (scalars override, append arrays extend, keyed tables replace by key).
• Verifies the outcome by running the resolver so the merged configuration is shown and inconsistencies can be corrected without inventing unsupported fields.

Quick Start

Ask an AI coding agent to customize Harness by running the harness-customize flow to override a specific installed skill after you say which agent or workflow you want to change and what behavior you want.
